Theory of flame propagation

Proceedings of the Symposium on Combustion, 1937
Summary In Mallard and Le Chatelier's treatment of flame propagation the problem is considered simply one of heat flow in which the unburnt gas is raised to its ignition temperature. Although crude, this treatment is able to explain a number of observations: limits of inflammability, effect of diluent gases on the latter and on rate of flame ...

Flame Propagation with Multiple Fuels

SIAM Journal on Applied Mathematics, 1982
The steady propagation of a flame through a premixed combustible mixture is studied for the case in which the mixture consists of two distinct fuels. We employ the method of matched asymptotic expansions to derive a solution for large activation energies, in which case both chemical reactions are confined to a thin layer.

Flame Propagation in Poiseuille Flow

39th Aerospace Sciences Meeting and Exhibit, 2001
We describe flame propagation in a channel subject to a Poiseuille flow within the context of a thermo-diffusive model under (i) adiabatic conditions, and (ii) in the presence of conductive heat losses at the walls. The curved two-dimensional lfames examined may be either assisted or opposed by the flow.

On Upward Propagating Flames

Combustion Science and Technology, 1994
Abstract The premixed flame propagating through a vertical channel and subject to buoyancy effects is analyzed. In the limit of strong thermal expansion of the burned gas and small normal flame speed, assuming the channel to be wide enough, the problem transpires to be closely related to the classical Rayleigh-Taylor problem for a long bubble rising ...

Flame Propagation in Tubes

The Physics of Fluids, 1962
An idealized theory of flame propagation is formulated to explain the effects of tube diameter, mixture composition, and direction of motion in a gravity field on the flame shape and ``speed of uniform motion'' of a flame front propagating through a stationary air-fuel mixture contained in a long tube. The effect of local flame curvature on flame speed

The Theory of Flame Propagation

The Journal of Chemical Physics, 1949
The characteristics of steady-state one-dimensional flames are expressed in terms of a set of first-order ordinary differential equations suitable for solution by differential analyzers or high speed digital computing devices. Arbitrary systems of chemical kinetics and reaction rates can be investigated.

Characteristics of flame propagation in a vortex core: Validity of a model for flame propagation

Combustion and Flame, 1997
Abstract Characteristics of flame propagation for methane-, propane-, and hydrogen-air mixtures and the validity of a model for flame propagation in a vortex core were investigated experimentally using a vortex ring generated by pulsing a quantity of the mixture through a circular nozzle.
